FORIFYIBROUS MATERIAL.

SPECIFICATION forming part of Letters Patent No. 302,023, dated July 15,1884-.

7 Application filed March 4, 1884. (No specimens.)

To all whom it may concern.-

Be it known that I, J OHN H. PEMBER'roN, a citizen of the United States,and a resident of Brooklyn, in the county of Kings, State of New York,have invented certain new and use 'ful Improvements in BindingCompositions for Fibrous Materials, of which the following is aspecification.

This invention relates to the manufacture of yarns from fibrous materialhaving little adhesive qualitiesas asbestus and has for its object toprovide a -means for causing the fibers of the asbestus, &c., to adheretogether, so as to make a strong yarn, without the admixture therewithof any substance detrimental to the purpose to which said-yarns are tobe applied. I I

It consists in thoroughly mixing with the asbestus, after it has beencleaned of all dirt, grit, &c., and carded, a binding material composedof pure lard-oil, water, borax, and starch, the proportions of which maybe varied according to the quality of the asbestus used. I have obtainedgood results with asbestus of fair' quality by mixing therewith abinding material composed of these ingredients, in the followingproportions, viz: ten gallons of lard-oil, twenty-five gallons of water,two pounds of borax, and three pounds of starch, the water beingpreferably heated to cause a thorough combination andadmixture of theingredients.

ers and the above composition sprinkled over it, using about one and ahalf gallon thereof to each one hundred pounds of asbestus. It is thenallowed to stand some time to become nearly dry, or may be quicklydried, if desired, on any suitable drying apparatus. Then it ispassed'through a willowing-machine and again carded before beingsubmitted to the finishing and condensing processes to make it intoyarn. This second carding operation is sufficient with my process tobring the asbestus into proper condition for the finishing andcondensing operations, 'whereas in the method of making such yarns asatpresent practiced, where a fibrous material of an adhesive nature ismixed with the asbestus, several condensing operations are necessary tocause a perfect admixture of the two different qualities of fiber.

The asbestus, after the i first carding process, is spread out in thinlay-' By the use of my composition the cards work clean with theasbestus, and the starch also preservesthe white appearance of theasbestus. The oil and other ingredients, if used alone, would give theyarn a dark color. It also has the effect of preserving the cards,acting somewhat as a lubricant to keep them pliable, they being quicklydestroyed when used to card the'asbestusyalone or asbestns mixed withfibrous binding material.

Other advantages resulting from the use of my composition are that lessWaste occurs in the carding process by reason of the greater tendency ofall the fibers to adhere together during such process, a much strongeryarn is produced therefrom than from a mixture of fibrous material withthe asbestus, and thepeculiar properties of the asbestus are not therebyimpaired.

The formation of the carded asbestus into yarn is not here described, asit forms no part of my invention.

This composition is also adapted to beused with other fibrous materialthan asbestus, as a binding material, it being particularly adapted tobind together short-staple fibers which have little or no naturaladhering quality.

Having now described my invention, what I claim, and desire to secure byLetters Patent, is

1. As a binding composition for fibrous materials, the followingingredients, combined in about the proportions named, viz: ten gallonsof lard-oil, two gallons of water, two pounds of borax, and three poundsof starch, substantially as described. p

2. As an improvement in the manufacture of asbestus yarnsythecombination, with the carded asbestus, of a binding material composed oflard-oil, water, borax, and starch, in about the proportions specified.

3. As an article of manufacture, asbestus yarn having as a bindingmaterial a composition of lard-oil, water, borax, and starch, in aboutthe proportions specified.

In testimony whereof I have hereunto set' my hand, at New York, countyand State of New York, this 3d day of March, 1884. I JOHN H. PEMBERTON.
